'It is well known that, in order to supervise electrical distributing systems, use is madeof luminous duplicating orminiature. telltale sys-, tems whose sections are illuminated when the corresponding line sections of the distributing system are alive. Such duplicating systems offer,

in-many cases, aneasy survey of the working condition of an electrical distributingsystem. If, however, great parts oithejline system are dead, for instance, .if the switch ofja main distributing point has dropped, the. supervisor cannot seefrom the diagram, up to what point the dead fore fediby meansof a circuit which is independentof the circuit for illuminating the sections, so that the illumination of the simulated switches may be made merely dependent on whether the corresponding switch of the .distributingsystemgbe opened or closed. I

A constructional example of the inventionis illustrated by the drawing. The general arrange-. ment of the distributing system itself is not shown, since it is exactly simulated by the duplicating system, so that the description of the latter. holds also good for the line. system of the distributing plant.

Fig. 1 is a diagram oia telltalesystem em.- bodying my invention; Fig.2 'is adetail view illustrating a. suitable arrangement of switches and circuits.

In Fig; 1; I. have shown a miniature diagram or reproduction of the distributing system, the numeral 1 designating a symbol which represents the source of current, 2. asymbol representing the line which receives current'from said source,- and 3, 4, 5, 6 symbols which represent correr spondingly arranged line sections of the distributing system. The switches are represented. by symbols such as the circles '7, 8, ,9, 10, 11, 12. The symbols '1 to 12 represent in a miniature replica, the. relative arrangement of the corresponding parts. of the distributingfiystem. For illuminatingthe line section symbols 2,3,4. 5,1,6, Lhave provided lamps '22.-.2,6 connected. in ,the

(Cl. 17'l.-311) manner shown, with an, auxiliary system which likewise is modelled on the distributing system andjfed bya currentsource'l3. The-lamps 2226' are controlled by auxiliary switches,3'l'.-42 located adjacentto the switch symbols:'l'l2. The secondor return conductors to .thelamps 22-26 are connectedto thesecond pole of the current sourcelS, and'have been indicated asa network designated by the numeral'l4. The symbols 7-12 indicate ina suitable .manner, the position or condition of the corresponding switches in the distributing system. In the working condition which has been takenas a. basis for the constructional example shown in Fig. 1, theswitches in the distributing system which correspond to the switch symbols 7; 8, and 11, and correspondingly the switches 37,38, and 41,0f the auxiliary or lamp. system arealso closed. Hence only the sections 2 and 3.are alive, so thatonlythe lamps 22 and'23 illuminatingsaidsections are supplied with current. Thesections 4, 5 and 6, however, are dark, and the supervisor would ,notbe sure whether, in case of thesections 4 or 6-being cutin, the-section 5 would also be made alive or not. Toovercomethis difilculty, I'have provided a second auxiliary system in which there are arranged, adjacent to theswitch symbols 'I'- 12-, illuminating. lamps 27-32. respectively, which .are all fed from the point t 33,, connected withthe current-source 13. Between this point and, the several lamps 27 32,' 'I have shown switches 47- 52 each of which is operated si-. multaneously with the corresponding switch 37-42 in,the first auxiliarysystem, say coupled mechanically with it, as indicated in the diagram Fig. 2.

The. switches of the system shown-inFig. l are. eithe per te b a up sor o m each switching in. the. distribut n 7 system is announced, Or said switches areoperatedautomatically with the aid of a remote control device. An arrangement suitable forthis purposeis indicated in Fig.2. Inorder to avoid crowding or, lines. the.mecha icalcpupli s h witches has. not been 1ndi ted. .F v n o; F E-.1 showsthat the ,twctelltale switches. associated with eachof the, line switches are alwaysinthe same position; that is, the switches at37, and .47. are. shown closed, as are also the switches, at .38 and 48 and, theswitchesat 41.and 51, the

will be understood that the illustrationtypical of one pair of associated switches and that the other pairs might be constructed and connected in the same way. The switches 40 and 50, which are associated with the line section symbol 5 and with the switch symbol 10 respectively, are mounted on the same pivoted arm 62, which is constructed as an armature adapted to be at- 1 tracted in one direction -or the,-otherby the relays 60 and 61 energized bybatteries 15, 16 respectively. By wires 17 and 18 respectively;

the relays 60 and 61 are connected with contacts on a stationary disk 64 adapted to be, 'engaged by a contact arm 63 mountedto rotate about the center of said disk 64. The disk'64 is loc ated at the-station at which the apparatus 0 f F,ig.. 1fis locatedand by a' line 67, the contact arrripj63ds connected witha similar contact arm 65 located in'the neighborhood of the switch IQ O ofthe distributing systemlo l, 105 The arm 3 0 65 cooperates with a 's'e ries of stationary contacts on a disk 66 and two of these contacts are connected by wires 19cm 20 with stationary contacts102, 103respectivelyadaptedto be engaged by a switch 101 which is movable in unison with the switch 100 of the distributing system. The switch 101-is adapted to engage, at the same time with the contacts 102, 103, grounded contacts 106 and 107 respectively. The switch arms 63and 65 are operated to rotate synchronously by any well known or. approved mechanism, and therelative location of these arms and of the contacts, is such that thearm 63 will be in conducting connection with the wires 17 and 18 respectively. at the same timethat the arm 65 is in conducting connection with thewires 19 andZO respectively. Itfwillbe understood that the arms 63,"65also ccntrol the connections of other relays such; as 60, 61, the contacts of the disks 64,66 which are shown unconnected in Fig. 2, being connected withother relays similar to60, 61 to operate pairs ofswitches such as 40.50 in connection with the other switch points of the installation indicated in Fig. 1. Fig. 2 shows that when the arm 62'fis attracted toward the right it will close'simultaneously the circuits controlledby the switches 40 and 50 respectively. When thearm 62 is attracted toward the left as illustrated said circuits are opened.

" the working condition shown in Fig.1, the simulated switch "or switch symbol 10 is dark, whereas the simulated switch or switch symbol ll'is illuminated. Though switch symbol 11 is placed between line section symbols indicating dead line sections, the switching operators attention will immediately be drawn to its final position, because it is illuminated. He knows that the line section corresponding to symbol 5 would be made alive, by cutting in the line switch corresponding to symbol 12, but not by closing the line switch corresponding to symbol 9. The invention permits, of course, of rendering conspicuous also the opened switches, though it is doubtful Whether a better survey will be obtained thereby, Instead of'cutting out the lamps for illuminating the switches, by interruption of other sets of two switches being shown in the current, one may also cover them by shutters: furthermore, it is also possible to mark the different positions of the switches by different illumination, for instance, in different colours or the like.

In order to mark the working condition of the sections and switches it is not absolutely necessary to illuminate the simulated sections by means oflamps. These may be substituted by electrically operated devices, which cover the simulated network entirely or in part, such as blinds, which according to their positions, render conspicuous parts of different colour or cover them. As to the carrying into efiect of the invention, suchdevices are as useful as the lamps described.
